MySQL 查看建表语句

查看mysql表结构的方法有三种：
1、desc tablename;
例如：
要查看jos_modules表结构的命令：
desc jos_modules;
查看结果：
mysql> desc jos_modules;
+------------------+---------------------+------+-----+---------------------+----------------+

| Field | Type | Null | Key | Default | Extra |
+------------------+---------------------+------+-----+---------------------+----------------+

| id | int(11) | NO | PRI | NULL | auto_increment |
| title | text | NO | | NULL | |
| content | text | NO | | NULL | |
| ordering | int(11) | NO | | 0 | |
| position | varchar(50) | YES | | NULL | |
| checked_out | int(11) unsigned | NO | | 0 | |
| checked_out_time | datetime | NO | | 0000-00-00 00:00:00 | |
| published | tinyint(1) | NO | MUL | 0 | |
| module | varchar(50) | YES | MUL | NULL | |
| numnews | int(11) | NO | | 0 | |
| access | tinyint(3) unsigned | NO | | 0 | |
| showtitle | tinyint(3) unsigned | NO | | 1 | |
| params | text | NO | | NULL | |
| iscore | tinyint(4) | NO | | 0 | |
| client_id | tinyint(4) | NO | | 0 | |
| control | text | NO | | NULL | |
+------------------+---------------------+------+-----+---------------------+----------------+

2、show create table tablename;
例如：
要查看jos_modules表结构的命令：
show create table jos_modules;
查看结果：
mysql> show create table jos_modules;
jos_modules | CREATE TABLE `jos_modules` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`title` text NOT NULL,
`content` text NOT NULL,
`ordering` int(11) NOT NULL DEFAULT '0',
`position` varchar(50) DEFAULT NULL,
`checked_out` int(11) unsigned NOT NULL DEFAULT '0',
`checked_out_time` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
`published` tinyint(1) NOT NULL DEFAULT '0',
`module` varchar(50) DEFAULT NULL,
`numnews` int(11) NOT NULL DEFAULT '0',
`access` tinyint(3) unsigned NOT NULL DEFAULT '0',
`showtitle` tinyint(3) unsigned NOT NULL DEFAULT '1',
`params` text NOT NULL,
`iscore` tinyint(4) NOT NULL DEFAULT '0',
`client_id` tinyint(4) NOT NULL DEFAULT '0',
`control` text NOT NULL,
PRIMARY KEY (`id`),
KEY `published` (`published`,`access`),
KEY `newsfeeds` (`module`,`published`)
) ENGINE=MyISAM AUTO_INCREMENT=145 DEFAULT CHARSET=utf8
3、use information_schema;select * from columns where table_name='tablename'
例如：
要查看jos_modules表结构的命令：
use information_schema;
select * from columns where table_name='jos_modules';
查看结果：
略。
如果要查看怎么建立数据表的命令用第二种方法最佳。
